# ty4z2008/Qix: a Markdown reading list for machine learning, PostgreSQL, Go and distributed systems

> Qix is not a library or a service. It is a curated set of Markdown files in one repository, and the only thing it installs is a clone. It is worth adopting as a reading map and nothing else.

## What Qix actually is, and the problem it addresses

Qix is a collection of Markdown files that point at other people's material. The repository holds algorithm.md, awesome.md, db.md, dl.md, dl2.md, ds.md, golang.md, node.md, pg.md and a style guide, plus a README that acts as a table of contents. The stated subject areas are machine learning and deep learning, PostgreSQL, distributed systems, database systems, Golang, and a Chinese translation of the node-mysql documentation.

The problem it addresses is link rot and scatter. If you are starting on distributed systems or PostgreSQL internals, the useful reading is spread across conference pages, personal blogs and course notes, and a list that someone else already assembled saves the first hour. That is the entire value proposition. There is no build system, no package, no API. The repository description lists the same topics, and the README's own headings are the index.

Who it is for: an engineer or student who wants a starting syllabus and does not mind that the list is a snapshot. Who it is not for: anyone who needs a library to import, a service to run, or a guarantee that a link resolves. The README itself carries a note that "There may be some incorrect information in the article," and asks readers to correct errors by email or pull request. Treat that as the honest description of the artifact.

## How the repository is organised, and where the reading lives

The README is a router. It groups links by topic and sends you to a file per topic: Chapter 1 and Chapter 2 for machine learning and deep learning, Chapter 1 for Golang, Chapter 1 for PostgreSQL, Chapter 1 for distributed systems, Chapter 1 for database systems. The repository root confirms those files exist as dl.md, dl2.md, golang.md, pg.md, ds.md and db.md. There is also awesome.md, algorithm.md, node.md and "Node style guide.md".

So the data flow is trivial and worth stating plainly: you open README.md, pick a topic, open the corresponding Markdown file, and follow links out to third-party sites. Nothing is fetched, indexed or validated at read time. There is no generated site in the repository, although the metadata lists a homepage at ty4z2008.github.io/Qix. The README does not document how that page is built or whether it mirrors the Markdown files.

This structure is why the project has no runtime failure modes, only content failure modes. A dead link is the failure. A stale recommendation is the failure. The repository cannot detect either on its own, and the README does not describe any automated link checking.

## Getting the files: git clone and reading the first chapter

There is nothing to install in the software sense. The README gives no install command and no package name, because the project is documents. The only way to get it is to clone the repository or read it on GitHub. A clone gives you the Markdown locally, which matters if you want to grep the lists or keep them after the upstream changes.

```bash
git clone https://github.com/ty4z2008/Qix.git
cd Qix
ls
```

The listing should show README.md alongside algorithm.md, awesome.md, db.md, dl.md, dl2.md, ds.md, golang.md, node.md and pg.md. From there, open the file for the topic you care about. For the machine learning track the README points at dl.md for Chapter 1 and dl2.md for Chapter 2; for PostgreSQL it points at pg.md; for distributed systems, ds.md.

The README also links the node-mysql Chinese document as node.md, and describes it as the translation corresponding to the node-mysql official document. If you only want that material, node.md is the file to open; the README does not say which of the other topic files are in English, Chinese, or a mix.

## The limitation that matters: a list is not a maintained index

The repository is not archived and the last push was on 2026-09-06, so the README and files have been touched recently. That does not make the links inside them current. A Markdown list ages in a way that code does not announce: the file still renders, the anchors still work, and the external targets rot silently. The README acknowledges this class of problem indirectly in its note about possible incorrect information, and asks for feedback through the issue tracker.

There is a second limitation that is easy to miss. The repository mixes a Chinese translation of node-mysql documentation with English-titled topic files. If you do not read Chinese, node.md is of limited use, and the README does not say which of the other files are in English, Chinese, or a mix. You find out by opening them.

The wrong-tool case is any task that expects executable behaviour. If you searched for Qix hoping for a query engine, a scheduler, or a database tool, this is not that. The name collides with other projects and the repository description is a topic list, which makes the mismatch likely. Nothing in the README describes software you can run.

## Alternatives: a curated list versus generated documentation

The closest alternative in kind is another curated awesome-style list on the same topics. The difference is editorial: Qix splits material into numbered chapters per subject, so the machine learning path has dl.md and dl2.md rather than one long file, while a single-file list keeps everything in one scroll and often sorts by category instead of sequence. Neither approach validates links, so the practical difference is how the reading is ordered, not whether it is current.

A different alternative is generated documentation, such as a docs site built from source with a search index and versioned pages. That approach can be kept in sync with the software it documents, and it can fail a build when a link breaks. Qix cannot do either, because the content is the links. If you need the node-mysql material specifically, the README points to the upstream official document as the source of truth and presents node.md as a translation. Reading upstream is the lower-risk choice when the two disagree, and the README's own framing supports that.

## Licence, upgrade cost and what to check before you rely on it

The README states an MIT License and links License.md. The repository metadata reports the licence as NOASSERTION, which means the automated classifier did not confirm a recognised licence identifier from the files. Those two signals disagree, and the README is not the authority on its own licence text. Open License.md and read it before you reuse anything. This is a description of what the files say, not legal advice.

Upgrade cost is close to zero in the mechanical sense and non-zero in the editorial sense. There is no dependency graph, no version pinning, no migration. You pull and you get the current files. The cost is that a pull can change what a chapter recommends, and there is no changelog in the README to tell you what moved. The only release listed is dated 2014-09-26, so releases are not how this project communicates change; commits are.

Before relying on it, check three things. Open License.md and reconcile it with the README's MIT claim. Open the specific chapter file for your topic and confirm the language and level suit you. Follow a handful of the links in that file to see whether they still resolve, because the repository has no mechanism that will do it for you.

## Conclusion

Adopt Qix if you want a single repository that points at machine learning, PostgreSQL, Golang and distributed systems reading, and you are willing to check every link yourself because the README warns that some information may be incorrect. Do not adopt it if you need a runnable library, a package, or a maintained index with automated link checking; there is no code here and the last push was on 2026-09-06, but the content is a set of Markdown lists, not a program. Before relying on it, verify that the individual files you care about still open, and read License.md rather than trusting the README, which says MIT while the repository metadata reports NOASSERTION.
